Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
Relative frequencies are gotten when you divide each class frequency
by the sum of the frequencies.
In your problem the sum is 100; so freq=20 means relative freq of 20/100=20%
The same for freq 30; rel freq is 30/100 = 30%
The same for freq 50; rel freq is 50/100=50%
